Please review this proposed patch to remove a redundant callback in the
truetype native scaler code. The urgency for this removal comes from the
fact that the callback occasionally falls foul of a race condition which
leads to an NPE:

The problematic code is the same in JDK9, JDK8 and JDK7.

Previous discussion with Phil Race (tentatively) confirmed that the
removed callback is redundant:

Red Hat support staff subsequently identified the race condition:
